If the Assumption of Mary is not directly in the Bible, why is it a Holy Day of Obligation? Hear Fr. Chris Alar explain that just because something isn't directly in the Bible doesn't make it false doctrine. 

All men were by nature foolish who were in ignorance of God,and who from the good things seen did not succeed in knowing him who is,and from studying the works did not discern the artisan;But either fire, or wind, or the swift air,or the circuit of the stars, or the mighty water,or the luminaries of heaven, the governors of the world, they considered gods.Now if out of joy in their beauty they thought them gods,let them know how far more excellent is the Lord than these;for the original source of beauty fashioned them.
